JOURNAL-LUBRICATOR.

Specification of Letters Patent.

Patented Jan. 23, 19117,

Application filed March 26, 1914, Serial No. 827,262. Renewed June 15,1916. Serial No. 103,868.

To all whom it may concern:

Be it known that I, Crrxnnns A. SIMMONS, a citizen of the United States,residing at Albany, county of Albany and State of New York, haveinvented certain new and useful Improvements in Journal-Lubricators; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to the lubrication of journals and moreparticularly to the lubrication of the journals of railway axles.

It is the object of the present invention to provide lubricatingmechanism adapted for introduction into a, standard journal box andhaving a drum faced with felt and arranged for rotation in contact withthe under-face of the journal to carry oil from the oil well and spreadit on the journal, this drum being perforated so that by centrifugalaction it may throw oil against the journal.

lt is a further object to provide such a iuounting of the rotating drumas will insure constant and reliable pressure against the journal and atthe same time, leave the bottom of the journal box unobstructed from endto end to facilitate the circulation of the oil and ready cleaning ofthe box.

To accomplish the foregoing objects, and to secure the benefit of otheradvantages inhering in applicants invention, the structural arrangementmay be as shown in the :u'companying drawings, wherein Figure 1 is asectional elevation through the journal box; Fig. is a transversesection on line of Fig. 1, and Fig. 3 shows the lubricating drui'n ofFig. 1 as seen from below.

ln the embodiment illustrated, a car journal 1 is inclosed in arectangular journal box of standard design, and having the usual sidecover 3. The bearing block t and wedge 5 are of usual construction.

)n one side of the journal box and preferably ast integral therewith area pair of lugs 6 and T (Fig. 3 under-cut to form a vertical guideway,and within this guide way and slidingiy mounted therein is a platform 8of such dimensions that it may be introduced through the opening ofcover 3 when the journal box is being assembled.

Platform 8 has a pair of downwardly extending legs 9 each provided witha transversely pro ecting stud or shoulder 10, and

at the top of the platform are a pair of cars 11 arranged to serve assupports for a transverse pivot bar 12 whereon the supporting frame ofthe rotating drum is pivotally mounted.

The drum frame 13 has a pair of downwardly extending curved arms leteach terminating in a straight finger 15 forming a seat for a helicallycoiled horizontal spring 16 which seats against the opposing leg 9 ofthe platform and is held in position thereon by shoulder 10. The frameis also provided with laterally extending cars 17 through which thepivoted bar 12 is passed so that the frame may swing about said bar. Theswinging frame isprovided with a pair of horizontal arms 18 (Fig. 3)forming a yoke and each shaped at its end to serve as a bearing for atransverse shaft 19 which passes through the drum from end to end.

The drum 20 is of cylindrical outline and preferably made of a singlebrass casting, and is closed at its ends except for a series of openings21 through which the oil 22 in the lower part of the box may gain accessto the inside of the drum. The drum is provided with a plurality ofperforations 23 and is covered with a layer of felt 24, or othersuitable yielding and absorbent mate rial, and this layer of felt hasperforations meshing with those in the metal drum. The felt ma be heldin place by encircling wire bands 25 (Fig. 3) lying in slots ordepressions in the felt.

With the arrangement above described, the drum presses yieldinglyagainst thejournal and is rotated thereby, and the felt covering of thedrum carries up oil from the oil well and spreads it on the journal, butin addition to this the oil runs in through the end openings 21 of thedrum and is thereafter forcibly thrown by centrifugal action through theperforations 23, thus spattering oil freely on the journal and in ameasure increasing the delivery of oil to the journal in proportion tothe speed of rotation. Also the drum with its felt covering acts as abuffer to polish the journal and keep it free from grit and bits ofmetal. The springs 16 are of such form as to 00- cupy but little space,and their shape and position is advantageous for holding the drum to itswork irrespective of irregularities in the track or jars and vibrationstransmitted to the journal box. By making the springs in helical form,fatigue of the metal is in large measure averted, and by providing aplurality of springs each effectively positioned to swing thedrum-supporting yoke about its pivotal center, a weakening or failure ofone spring does not render the oil device inoperative.

With the arrangement described, the mechanism is entirely supported fromthe side of the journal box and leaves the oil well substai'itiallyunobstructed from end to end, so that it maybe readily scraped out andcleaned when necessary.

I claim:

1. The combination with a car journal and a journal box, of alubricating drum having an absorbent covering; and engaging with theunder-face of said journal, said drum being hollow and provided with endopenings for the admission of oil, and a frame pivotally mounted forsupport by the side of the journal box and carrying said drum, saidframe having downwardly extending arms, and helically coiled springsbearing horizontally against said arms to hold said drum yieldingagainst its journal.

2. The combination with a car journal and a journal box, of a platformdetachably supported by a side wall of said box, said platform servingas a support, a drum having an absorbent covering and bearing againstthe lower face of said journal, a frame supporting said drum andpivotally mounted on said platform, said frame having downwardlyextending integral arms, and helically coiled springs arrangedhorizontally in engagement with said arms to control the pressure withwhich the drum bears against its journal.

8. The combination with a car journal and a journal box of a platformremovably mounted against the side of said journal box to serve as apivotal support, a frame pivoted to said support and having downwardlyextending arms, coiled springs engaging said arms and bearinghorizontally against the lower ends of said platform, a drum with anoil-absorbent face mounted to turn in said frame, said drum being hollowand having perforations through which oil may be thrown from the insideof the drum against the journal to be lubricated.

4;. The combination with a car journal and a journal box of lugs on theside of the journal box forming a vertical guideway, a platformslidingly mounted in said guideway and having legs and ears, a pivot barsupported by said cars, a swinging frame mounted on said pivot bar andhaving downwardly extending arms, a spring between each of said arms anda leg of said platform, said frame being shaped to form a yoke, arotating drum mounted in said yoke and provided with an absorbentcovering held in yieldinp; engagement with said journal by said springs,openings in the end of said drum and perforations through the cylinderface of said drum and its felt covering, whereby oil may be thrown bycentrifugal action from the inside of the drum through said perforationsagainst the journal to be lubricated.

In testimony whereof I aflix my signature in presence of two witnesses.
